ABSTRACT:
A light-sensitive mixture that contains as essential constituents (a) a diazonium salt polycondensation product, (b) a free-radical polymerizable compound, (c) a polymerization initiator which forms free radicals under the action of actinic radiation and (d) a water-insoluble polymeric binder which is soluble in organic solvents and in aqueous alkaline solutions, where the binder is a reaction product of an intramolecular anhydride of an organic polycarboxylic acid with a hydroxyl-containing synthetic polymer, is preferably used for preparing planographic printing plates which combine high image resolution and an extended print run.
